[ Details of a failed upgrade from 4.9 to 5.2 snipped... ]

I'm probably missing something, but I vaguely recall someone having
said we try to support an upgrade from 4-STABLE to -current.  If I'm
not remembering that right ignore this...

If I am remembering that right don't the statfs issues break that,
or at least make it something not to be attempted by mere mortals
and perhaps worth a mention in UPDATING?  Based again on possibly
flawed recollections I thought general concensus was when upgrading
from pre-statfs change systems to post-statfs changes you should
not only make sure you do the 'buildkernel' before 'installworld',
but you should also make sure to reboot with that kernel before
doing the 'installworld'.  But it's installworld that puts most of
the new goop in /boot that goes looking for the kernel in the right
place, and the thought of a 5.X kernel using 4-STABLE variants of
the things it takes to get to single-user mode sounds scary.
